Chennai Metropolitan Area (CMA) is a metropolitan area in Tamil Nadu state, consisting of the state capital Chennai (previously known as Madras) and its satellite towns. Developing over a period of about 20 years, it consists of 8 municipal corporations and 14 smaller municipal councils. The entire area is overseen by the Chennai Metropolitan Development Authority (CMDA), a Tamil Nadu State Government organisation in charge of town planning, development, transportation and housing in the region. The CMDA was formed to address the challenges in planning and development of integrated infrastructure for the metropolitan region. The areas outside Greater Chennai Corporation (Chennai District) like Kanchipuram and Tiruvallur have lacked organised development.
The (CMA) comprises the city of Chennai, 8 Municipalities, 11 Town Panchayats and 179 Village Panchayats in 10 Panchayat Unions. The CMA has an area of 1,189 km².. It includes the whole of the Chennai District, along with the Ambattur, Gummidipoondi, Madhavaram, Ponneri, Poonamallee and Tiruvallur taluks of the Tiruvallur District, and the Kanchipuram, Sriperumbudur and Tambaram taluks of the Kanchipuram District.
The CMA falls in three Districts of the Tamil Nadu State viz. Chennai District, part of Thiruvallur District, and part of Kancheepuram District. The extent of the Chennai District (covered in Chennai Municipal Corporation area) is 426 km2 and comprises 55 revenue villages in 10 Taluks [viz. (i) Tondiarpet Taluk, (ii) Perambur Taluk, (iii) Purasawalkam Taluk, (iv) Egmore Taluk, (v) Mambalam Taluk, (vi) Guindy Taluk, (vii) Mylapore Taluk, (viii) Velachery Taluk, (ix) Aminjikarai Taluk and (x) Ayanavaram Taluk. In Thiruvallur District out of total district area of 3427 km2, 637 km2. in Ambattur, Thiruvallur, Ponneri and Poonamallee taluks fall in CMA. In Kancheepuram District out of 4433 km2, 376 km2 in Tambaram, Sriperumbudur and Chengalpattu Taluks fall in the metropolitan area.
CMA region has about 3,000 water bodies, most of which have been encroached upon by real estate dealers and small communities.

The first plans to expand the CMA were proposed by the CMDA in 2011. The need for expansion arose as several nearby settlements such as Sriperumbudur, Kelambakkam, Tiruvallur and Maraimalai Nagar had been undergoing rapid development and had to be incorporated under the CMDA planning strategy. Also, the planning bodies of other metropolises in India such as Bengaluru, New Delhi and Hyderabad had already redefined their respective metropolitan regions to include much larger areas and corresponding regional planning was being done. The CMA, however, hasn't been altered since it was first defined in 1974. The area was limited to 1,189 km2 (459 sq mi) which is among the smallest in the country.
In July 2012, the CMDA suggested two options to the Government of Tamil Nadu for expanding the area:
- The first option includes whole of the Chennai district, Madhavaram, Ambattur, Poonamallee, Ponneri, Gummidipoondi, Uthukottai, and Thiruvallur taluks of the Tiruvallur district, and Alandur, Pallavaram, Tambaram, Sholinganallur, Chengalpattu, Thiruporur, and Sriperumbudur taluks of the Kancheepuram district extending up to 4,459 km2 (1,722 sq mi).
- The second option includes the whole of Chennai, Tiruvallur and Kancheepuram districts and the Arakkonam taluk of Vellore district and extends to a total of 8,878 km2 (3,428 sq mi).
Chief planners of the CMDA have suggested that the second option is more feasible. Another planning model, similar to the National Capital Region was also examined by the CMDA. In order to plan for balanced regional development, developing a larger road network, implementing an integrated transport plan and identifying a Chennai Mega Region have become necessary.
On 3 July 2017 the Government of Tamil Nadu's minister for housing and urban development, Udumalai K. Radhakrishnan announced its intention to expand the CMA to 8,878 km2 (3,428 sq mi). The extension will cover all of Kancheepuram and Tiruvallur districts and Arakkonam taluk of Vellore district, as proposed in July 2012. Having completed a feasibility study, a "strategic regional plan" was now required, and completion of the whole process was expected by July 2018.
On 22 January 2018 the Government of Tamil Nadu issued order G.O. (Ms) No.13 to "declare the intention to include additional areas in the Chennai Metropolitan Planning Area" under section 2, clause (23-a) of the Tamil Nadu Town and Country Planning Act, 1971 (Tamil Nadu Act 35 of 1972). The additional areas to be included were as proposed by the CMDA in 2017. Under Tamil Nadu Act 35 the Tamil Nadu government is required to allow reasonable opportunity (two months according to §10.3) for inhabitants, local authorities and institutions in the area to comment upon or object to such an expansion proposals. Although less than 100 objections to the expansion plans were received, a public interest litigation action was launched at the Madras High Court in March 2018.
